隧道运营通风 meaning in Chinese
permanent ventilation of tunnel
Examples
- Code for design on operating ventilation of railway tunnel
铁路隧道运营通风设计规范 - Finally , based on the survey on the ventilation of double ( rack tunnels in operation representative parameters were selected and a series of computations were carried o ' ut to examine the train passing capacity of tunnels with different lengths and slopes
最后，根据对我国双线铁路隧道运营通风的调查分析，选择具有代表性的参数，利用数值计算程序，对不同长度和坡度的隧道在自然通风情况下列车的通过能力进行了模拟计算。 - Because there are small openings and the three cracksin the concrete lining of gas tunnel , the gas should intrude into the gas tunnel built . this effect will endanger the transport safety . the authors study on the operation ventilation technology in the gas tunnel and put forward an economical , safety and effective ventilation plan , and therefore furnish a theoretical basis for the gas tunnel ventilation design in the future
由于瓦斯隧道混凝土衬砌本体中的细小孔隙和“三缝”等缺陷的存在，建成后的瓦斯隧道必然受瓦斯侵袭，这对运营安全危害极大，为此，本文对瓦斯隧道运营通风技术进行了认真研究，提出了经济、安全、有效的通风方案，为未来瓦斯隧道的通风设计提供了理论依据。 - By analyzing the relation between the train passing capacity and tunnel length as well as tunnel slopes the upper and lower limits for installing mechanical ventilation in railway double track tunnel have been determined , which provides science foundations for the formulation the ventilation design norm for railway double track tunnels in operation
通过对列车通过能力与隧道长度和坡度关系的进一步研究，得出了内燃牵引双线铁路隧道设置机械通风的上、下界限，为双线铁路隧道运营通风设计规范的制订提供了科学依据。 - Then a one - dimensional unsteady incompressible flow with moving pollutant source model was proposed . the continuity equation , momentum equation and convection - diffusion equation were discredited using finite volume scheme . thus a software for predicting the air velocity and pollutant in railway double track tunnels was developed
接着，根据双线铁路隧道运营通风的特点，建立了一维不可压缩非恒定流和流动污染源的物理模型以及山相应的连续性方程、动量方程和对流扩散方程构成的数学模型；在此基础上，利用数值计算方法，编制了一套双线铁路隧道运营通风的数值计算程序。
